Summary

Hypericum galioides, commonly known as Bedstraw St. Johnswort, is a slender, branching perennial shrublet native to wet pine flatwoods, savannas, and seepage slopes in the Southeastern United States. It is found from North Carolina to northern Florida and west to Texas, but is absent from most of the Mississippi delta. This species typically grows up to 5 feet tall and features linear to oblanceolate leaves. From June to August, it produces small, showy yellow flowers with numerous stamens, ranging from 60-120 per bloom, which attract pollinators.

Bedstraw St. Johnswort is valued for its ornamental flowers and its ability to thrive in wet to moist habitats, making it a suitable choice for rain gardens, wetland restoration projects, and naturalized areas. It prefers full sun to part shade and requires moist to wet soil conditions with good drainage. While it is not commonly used in traditional garden settings, its adaptability to wet environments and contribution to biodiversity make it an important plant for ecological gardening. Care should be taken as it can spread in favorable conditions, potentially becoming aggressive in some areas.CC BY-SA 4.0
